Title: Improvements in and relating to tap changing transformers
IPC: H01F29/04
Filed: 1955-12-13
Abstract: 776,966. Transformers. GENERAL ELECTRIC CO. Dec. 13, 1955 [Dee. 14, 1954], No. 35769/55. Class 38 (2). An on-load transformer tap-changing system comprises a transformer having a primary, a secondary and a tapped tertiary winding 36, 30, 39 respectively, on a common magnetic core, the tertiary winding being connected at one end or at both ends with one of the main windingspreferably the secondary winding-and being of smaller cross - sectional area than that winding. A tertiary winding 39 of a tap changing transformer 31 is provided with a number of tappings 41 ... 49, this winding being connected, with a series resistance 57, in parallel with the main secondary winding 30. The voltages between taps are taken off by way of a usual centretapped reactor 54 and applied via a reversing switch 56 to the primary winding 52 of a further transformer 33, the secondary winding 32 of which is connected in series with the main secondary winding 30 of the tap-changing transformer 31. The reversing switch 56 enables the output voltage between leads 34, 35 to be the sum or difference of the voltages of the two secondary windings 30, 32 as desired. The resistance 57 preferably has a negative resistance-current characteristic and is provided to prevent large voltages from appearing between ends 58, 59 of the windings 39, 30 and also to prevent appreciable circulating current from flowing in the windings. The use of such a tertiary winding enables the main secondary winding to be constructed in the normal manner with laminated conductors, the strands of which are transposed relative to each other throughout the winding, the tertiary winding may also be laminated, if desired, but need not have transpositions made therein.

The capacitors are preferably charged via an inductor L. The invention may be applied to direct current regulators and series inverters.
Patent GB-980356-A (GB)
Title: Improvements in or relating to processes for separating organic compounds
Inventor: KATSCHER ERNST
IPC: C07D213/78
Filed: 1962-09-24
Abstract: A process for separating picolinates, nicotinates and/or isonicotinates from aqueous solutions of two or three of these compounds comprises precipitation in two stages with the compounds in the calcium form and in the acid form.  The aqueous mixture may be derived from the oxidation of pyridine bases and may contain sulphuric acid and pyridine bases and the compounds may be in the acid form.  The mixture is freed from sulphuric acid and pyridine bases and iron or magnesium salt impurity by the addition of calcium carbonate and separation of the precipitate.  Calcium picolinate and nicotinate may be first precipitated by adjustment of the pH and the isonicotinic acid precipitated from the separated solution or alternatively the isonicotinic acid is precipitated and removed and the calcium picolinate and nicotinate precipitated from the solution. Examples describe the treatment of mixed acids derived from the oxidation of alkyl picoline bases by the adjustment of pH with calcium carbonate or sulphuric acid.  The picolinic acid may be further recrystallized from solvents such as benzene, toluene or alcohol.

Title: Improvements in and relating to the purification of combustible gases
IPC: C10K1/18
Filed: 1933-12-27
Abstract: 430,989. Distilling wash oils. HOLMES & CO., Ltd., W. C., COOPER, C., and HENSHAW, D. M., Whitestone Iron Works, Huddersfield. Dec. 27, 1933, No. 36321. [Class 32] [See also Group XII] All the volatile hydrocarbons such as benzene, and a substantial proportion of carbon bisulphide are removed from combustible gases by scrubbing with a volume of wash oil unsaturated with respect to naphthalene of the order of 30 gallons per 1000 cubic feet and a proportion of the hydrocarbons are afterwards returned to the gases. The used wash oil may be only partly stripped and returned into contact with the gases while containing a substantial proportion of the absorbed substances, or some of the benzene recovered by a complete stripping is revaporized into the scrubbed gas. Wash oil passes from a washer 1 through a heat exchanger 3 in which it is cooled by indirect contact with stripped oil returned to a cooler 2. The warmed oil traverses a preheater 12 and the greater part then enters a still 7 through sprayer 21, some however passing to sprayer 20, which may alternatively be supplied through a byepass 38, and this quantity is controlled by a valve 41 in dependence on the temperature of the vapours passing to a condenser 24. Steam may be admitted to the still from a high pressure main 37 or from a source of exhaust steam, and the still maintained at 100‹ C., by condensation of the steam. Alternatively inert gases or a partial vacuum may be employed. Vapours are also drawn off from the still by a pipe 29 and condensed in a condenser 30. A small quantity of oil is withdrawn through a pipe 43 to a naphthalene recovering plant comprising a preheater 45, a still 47 in which it is completely stripped by live steam and vapour fractionating condensers 53, 54 in which naphthalene and like difficultly volatile bodies are recovered. Specifications 283,028, 293,702, 300,964, [all in Class 55 (ii)], 357,712, 366,646, [both in Group XII], and 393,041 are referred to.

Abstract: 1,044,758. Continuous-casting machines; breaking; shearing; rolling. DAVY & UNITED ENGINEERING CO. Ltd. Aug. 4, 1965 [Sept. 9, 1964], No. 36924/64. Headings B3E, B3F, B3M and B3W. A continuous-casting mould 11 has at least three interconnected billet cavities 12, 13, 14, e.g. of rectangular section, the axes of alternate cavities 12, 14 lying in a plane and the axis or axes of the remaining cavity 12 or cavities is or are displaced from that plane. Adjacent sides 12A, 13A of adjacent cavities lie in planes which may coincide. If they do not, the plane of each such side may extend into the adjacent cavity, Fig. 1 (not shown). The billets are sheared from one another by passing the casting between a pair of cylindrical rolls 17, Fig. 1 (not shown), so that the webs formed by the mould interconnecting-passages 15, 16 are sheared and the billets are forced to a side-by-side relationship; alternatively, shearing rolls 18, 19, Fig. 2 (not shown), with hardened edges 20, are arranged so that one roll contacts each inner side of a billet.

Title: Optical surveying instrument tracking system
IPC: H01S3/02
Filed: 1972-08-08
Abstract: 1381157 Surveying apparatus BLOUNT & GEORG Inc 8 Aug 1972 [20 Sept 1971]  36949/72 Heading G1F [Also in Division H4] A surveying system comprises a housing pivotally mounted on a support and containing a laser and an infrared detector, a remote target emitting infrared waves such that the housing tracks the target and the elevation of the point at which the target is located being determined by the position of the laser beam on the target. In the described embodiment a laser beam 30, Fig. 1 is maintained in alignment with a stadia rod 26 by means of an infrared beacon 24 on the rod. The laser beam produces a spot of light 32 on the rod and enables determination of the desired elevation height. The beacon 120, in Fig. 9, comprises three diodes emitting in different directions so that the receiver can still operate if the rod is twisted during use. The signals received by diodes 42a, 42b in housing 18, Fig.1 of the receiver are mixed with a reference signal and the resulting 20HZ signals applied to amplifiers 190, 164 providing the difference and the sum of the signals respectively. The sum signal is passed to a zero crossing detector 166 and the resulting square wave signal is applied to a differcntiator 200. The signal from device 200 is used to sample the sum signal. Provided signals are being received from the beacon, signals from amplifier 172 will be present and these are used to disable device 204. If no signals are being received, the device is activated and prevents stray charge from building up in the circuit. In this mode relay 174 switches a reference voltage to servo amplifier 178 and causes motor 80 to continually rotate housing 18 until signals are received from the beacon. When signals are being received relay 174 switches the error signal from the difference channel to the servo-amplifier so that the motor homes on to the beacon. Switch 176 may be moved to a manual position in which motor 80 may be controlled by manual device 182. Servo amplifier 178 can be compensated for different beacon ranges by device 210. The beacons may alternatively be mounted on the blade of an earth moving machine and the system may be utilized in other surveying operations. (For Figures see next page)
